Immediately transfer cooked rotini to an ice bath for 2-3 minutes to stop the cooking process and maintain a perfectly al dente texture that won't turn mushy in the dressing.

Add the vinaigrette while pasta is still warm so it absorbs the flavors better, but wait to mix in fresh mozzarella and delicate herbs until just before serving to prevent them from becoming soggy.

Use a 3:1 ratio of olive oil to red wine vinegar, then add a pinch of sugar to round out the acidity and marry all the flavors together harmoniously.

Dice your cucumber, tomatoes, and red onion into similar-sized pieces as your rotini so each bite contains balanced proportions of pasta and fresh vegetables.

Tear your fresh mozzarella into bite-sized pieces just before assembly and use room-temperature cheese to avoid it becoming tough; add it as the final ingredient to maintain its creamy texture.
